Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points. If more applicable or accurate data are available, they should be substituted. For spectrum examples, see The mounting devices shall not have significant resonances in the test frequency range. Caution is necessary to avoid excessive pressure or mounting methods that could influence the characteristics of the product. Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points.

This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container. If more applicable or accurate data are available, they should be substituted. Test duration, random spectrum, and damage criteria are to be specified by the user. Mount the accelerometer to either the top or bottom of the test surface, as close to the test item as possible, or in a location which produces data representative of table motion.

Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points. Other, more suitable test procedures should be used for this purpose. Use a stroboscope; sensors and readouts; and visual, auditory, or other means as applicable to determine these resonances.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The instantaneous magnitudes of random vibration are not prescribed for any given instant in time, but instead are prescribed by a probability distribution function, the integral of which over a given magnitude range d35580 give the probable percentage of the time that the magnitude will fall within that range.

Any resonances with transmissibilities of 2 or greater may be considered significant. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior dd3580 use. If more applicable or accurate data are available, they should be substituted. Significance and Use 4. This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container.

Dwell time, acceleration level, and damage criteria are to be specified by the user. Record any resonant responses of the product, repeat the cycle if necessary.

This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container. Record any resonant responses of the product. D Terminology of Packaging and Distribution Environments.

Whenever sufficient products are available, five or more replicate samples should be tested to improve the statistical reliability of the data obtained see practice E Active view current version of standard. Operating personnel shall remain alert to potential hazards and take necessary precautions for their safety.

ASTM D – 95() Standard Test Methods for Vibration (Vertical Linear Motion) Test of Products

Two alternate test methods are presented:. A stroboscope or video system may be beneficial for visual examination of the specimen under test. The two test methods are not necessarily equivalent and may not produce the same results. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Other, more suitable test procedures should be used for this purpose.

Historical Version s – view previous versions of standard. For sine testing, the frequency sweep may be interrupted or reversed if necessary for short time periods in order to properly identify a resonating component.

The determination of the resonant frequencies of the product may aid the packaging designer in determining the proper packaging system to provide adequate protection for the product, as well as providing an understanding of the complex interactions between the components of the product as they relate to expected transportation vibration inputs.

Two alternate test methods are presented: It is recommended that the minimum frequency range be from 3 to Hz, the overall amplitude s of the spectrum be not less than 0. For sine testing, if different frequencies are recorded for each resonating component on the upsweep as compared to the downsweep a typical situationrecord both frequencies and the corresponding sweep direction.
